Abstract
In this work, CdS/Pt-TiO2were produced by incorporating Pt/CdS on TiO2 nanoparticles with chemical reduction and hydrothermal method using chloroplatinic acid (H2PtCl6) and CdCl2/CH4N2S as precursors, respectively. The Field Emission Electron Microscopy (FESEM), UV-Vis Diffuse Reflectance Spectroscopy (Uv-Vis DRS), X-Ray Diffraction (XRD) were applied to characterize the photocatalyst samples. Results indicated by EDX spectra and elemental mapping depicted the decoration of Pt and CdS on TiO2. Depositing Pt/CdS on TiO2 enhanced the redshift in the UV-Vis DRS analysis. The photocatalytic performance 1 g of CdS/Pt- TiO2 could reduce the 500 ppm COD in 1 L palm wastewater by 71.4% elimination under mostly visible light irradiation in 3 h. The increased photocatalyst efficiency was caused by synergy effects due to the capability of Pt acts as an electron trapper that can eliminate the recombination of photogenerated electron-hole pairs and decorating CdS on TiO2 could result in photocatalyst which shifts towards the visible light region.
